Tighter and taller.

Giordana is going tall. With their Men's EXO Tall Cuff Compression
Sock, you get both style points and recovery advantages whilst your feet
and lower legs are covered.

Compression is all the rage these days. So is the philosophy of
‘marginal gains.’ Put the two together and you know why these foot
covers are popular. Some like wearing them pre-ride, some post-ride,
while others wear them the whole day through.

The particulars of this sock are fairly straightforward. The sock is
woven from a blend of Meryl Skinlife and Lycra. The Meryl is there
because the fiber is light, thin, fast-wicking, and quick-drying. The
Lycra is there to keep it snug, both around your feet and your ankles.
To keep it super snug around your feet, there's a mid-foot band; sliding
socks are no fun, not only can they be annoying, they can chafe. The
weave, which is different than the weave in Giordana's Mid Cuff EXO
sock, is designed to create the compression characteristics you need.

The Giordana Men's EXO Tall Cuff Compression Sock has a cuff height
of six inches. The socks are left and right specific. Sizes run from
Small to Large.

Perfect

Familiarity: I've used it several times

These are the perfect compression sock for the road. Some compression socks are so dang tight you have to wrestle them on, but with these they provide just the right amount of gradual compression. Perfect for summer riding and keep your feet feeling fresh all day. One of my favorites.

Top notch sock!

Familiarity: I've used it several times

Fit: True to size

This sock is tall, with just the right amount of compressive material. There is no struggle to pull the sock on or take off. It feels great on the bike and really awesome for those of us with high arches. I will buy more.

Great but watch size

Familiarity: I've used it once or twice and have initial impressions

I'm a 10.5US and the size chart puts me at the end of the medium. I have to pull these on tight for them to fit. If you run near the edge of a size go up a size. This just gives me an excuse to now purchase the white ones in size large. Damn you cycling apparel shopping addiction!!!
